85% high alumina cib yog cov khoom nruab nrab refractory nrog cov alumina cov ntsiab lus ntawm ib ncig ntawm 85%. Ua los ntawm cov ntaub ntawv raw nrog cov ntsiab lus zoo siab, xws li bauxite, dhau los ntawm kev molding thiab regrination. Siab siab thermal ruaj khov, nrog hluav taws kub tiv thaiv dhau 1770 degree. 85% High Alumina Cib kuj tseem muab faib ua cov pob zeb siab sib xyaw (piv txwv li cov cib siab (piv txwv li cov tshuab hluav taws xob siab (piv txwv li G-puab cib).
Raws li cov peev txheej sib txawv thiab cov khoom lag luam, 85% High Alumina Bibina cov zaub mov alumina (xws li monohydrate alumina, trihydrate alumina, thiab lwm yam); Cov pab pawg uas ua kom cov neeg ua si (sib dhos, suav nrog Kyanite, Rhaurodomrosite, Sillimanite, thiab lwm yam); Artificially synthesized raw cov ntaub ntawv, xws li muaj kev muaj keeb kwm alumina, fusion mullite, feem ntau muab faib rau hauv Shanxi, Henan, Guizhou, Shandong thiab lwm qhov chaw. Lub siab alumina vanadium av tsim yog tsuas yog sib xyaw ntawm ob lub tais, uas yog boehmite (- Al2o3 tebchaws.
Qhov laj thawj tseem ceeb rau cov tsos ntawm cov xim tsis muaj xim loj alumina yog vim qhov kub ntawm cov cua thawj, uas rov qab cov xim hlau thiab titanium ions. Ntawm qhov kub qis dua, cov hlau tsis tshua muaj hlau thiab titanium ions yauv olovo oxidation thiab decolorization.
Tsis tas li ntawd, lub siab Alumina cov cib muaj nyob ze rau lub thawv hluav taws kub ua haujlwm vim qhov kub ntawm huab cua kub, uas tiv thaiv kev rov kho cov huab cua; Thaum lub sij hawm txias txheej txheem, maj txias txias yog siv los de oxidize thiab decolorize cov hlau pheej yig thiab titanium ions.
According to the difference in the content of Al2O3, high alumina bricks are commonly used with contents of 48%, 55%, 60%, 65%, 73%, 75%, 85%, and of course, those with higher contents are classified as corundum.
